How It Works
The toxic principle in macadamia nuts has not been identified despite decades of study. Toxicity causes a non-fatal but distressing syndrome characterised by weakness, tremors, hyperthermia, and vomiting. The minimum toxic dose is approximately 2.4g/kg of raw macadamia nuts, though signs have been reported at lower doses. Recovery is typically complete within 48 hours with supportive care.
